Taiwan is scrambling to secure its communications with the outside world against an attack by China, but even in peacetime cannot quickly repair critical undersea internet cables and lacks suitable satellite backups, experts and officials say.
China, which has never renounced the use of force to bring Taiwan under its control, has ramped up military and political efforts to force the democratically governed island to accept its sovereignty.
The invasion of Ukraine has lent new urgency to Taiwan's efforts to bolster its security, especially against Chinese cyber attacks or attempts to sever any of 14 cables that connect it to the global internet.
